Contact Lenses, Advantages and Disadvantages

Contact lenses are a very common manner in which patients choose to correct their vision. They have several advantages over glasses, but tend to lead to further problems too.
Advantages include better vision on account of correction on the outside of the eye, and handle field of vision.
Several problems can occur due to contact lens wear too, so care should be taken to avoid these problems. Many doctors refer their patients to ophthalmolgists for evaluation and management of their lens related problems.
How can contact lenses damage the eye?
Contacts may cause many problems in the eye, but only a couple of commonly encountered diagnoses can cause severe problems. Giant papillary conjunctivitis, punctate keratopathy and ulceration will be the three most problematic issues.
Giant Papillary Conjunctivitis (GPC)
GPC occurs because of overwear of contacts, either too many hours daily, or a lot of days back to back. Symptoms include itching, inability to wear lenses all day long, and mucous discharge.
Punctate Keratopathy
Overwear also can result in a problem on the outside with the cornea, the place that the top layer of cells are damaged. The eye doctor sees tiny pinpoint scratches on the cornea a result of decreased oxygen to prospects cells.

How will we prevent contacts problems?
The most crucial thing for patients to perform is control their lens wear. Although many lenses are created and approved for overnight wear for between 2 and a month, most eye doctors recommend nightly removal and cleaning. The single most typical reason for contacts related problems is overwear, along with a large study indicated that overnight wear is fourteen times prone to cause ulcers than another risk factor.
Are there safer alternatives to wearing contacts?
Of course, glasses would be the safest method to correct vision without running the potential risk of contacts. Since glasses don’t touch the eye area, they can’t lead to further problems. On the other hand, being that they are away from your eyes, the don’t give vision that’s as sharp as lenses. Rigid or hard contact lenses are even better since they float at first glance in the eye, effectively smoothing out any rough spots, giving the most effective vision.
Recent studies also reveal that LASIK has less risks than contacts, while it’s a surgery. It is considerably more common for disposable lenses to cause infection, inflammation etc vs. LASIK.
